My invention is concerned with improvements in double glass sashconstruction of the t pe More specifically, it is an object of myinvention to providea double glass sash construction comprising a pairof generally rectangular rim members, which are positioned to form aframe having a channel-like recess for receiving and clamping the edgesof the glass panes, Tastening elements to hold the rim members inclamping position and resilient separator and glazing means positionedat the edges of the panes for spacing the edges of the panes from eachother and from the rim members, wherein the rim members, the separatorand glazing means are shaped and positioned to accomm'o date panes ofvarying thickness.

It is a further objbt f invention t6 pro= vide a double glass sash 'ofthe type described which when installed in an aperture in a'vhi'cle wallwill provide a window which is hermetically sealed irrespective ofcommercial variations in the thickness of the glass and in which theframe forming rim members are positioned between the inner and outervehicle wall members with theglazing strips covering the normallyexposedsurfaces of said rim members. 7

It is another object of. my invention to 'pro vide a novel sashconstruction which may be economically manufactured and which is readilyand easily assembled and installed ina sash opening.

These and other objects will be apparent from the description of thepreferred form of my -in= vention,- which is shown, by way ofillustration, in the accompanying drawings, wherein:

Fig. 1 is a face View of a double 'glass'sash com structed in accordancewith my invention;

Fig. 2 is a .perspective sectional view through one of the walls of thesash;

Fig. 3 is a transverse sectional view taken on:

the line 3-3 of Fig. l;

Fig. 4 is a perspective sectional view through one of the rim membersiofthe frame;

Fig. 8 is a perspective sectional view through ee edge spacing member;and i Fig. -7 is a perspective sectional view throng one of the glazingstrips. i

The preferred form of my invention, as illustrated in the diawing comrise a name 'i'orlnd by complementary rim members 1 0 and I11, which aregenerally rectangular and which *fgifind continuously around the-edgesof the two glass panes i2 and I3. a l

The rim members 10 and "l I are provided with inwardly extending flanges14 and 1 5 and out wardly extending flanges l6 and M, respectively. Theyare also provided with short laterally directed web's l8 and I 9andshort outwardly directed flanges 2'0 and 2] at the confronting edgesof the webs 18 and 19. The flanges Ill and 2| are spaced apart slightlyin generally parallel relation to the median plane of the sash. Theflanges 1-6, H and 20,21, together with the webs l8, 19 form outwardlydirected pocketstto receive connecting'bmcks 22.

The connecting blocks 22 "are provided on the four sides of the sashbutdo not extend around the curved cornersof the same as indicated inFig. 1. The connecting blocks 22 (F1915) "corn prise a base portion 23and inwardly extendin Side projections 24, 25; which fbfiil Centralgroove 25. The inwardly extending side m jections 24 and 25 are receivedin the pockets formed between the flanges I16, and [1, 21 0!. the rimmembers 10 and *M. The flan e members 2o 'and 2l of the rim members wandl I are we cei v'ed in the groove z'e of the connecting block's 22. Theinner faces 2! and 28 of the Side ploj ections 24, of the-connectingblock's -22 are in abutting, olainbing relation with the falh'g 'sbits29 and 30 presented'by the short flanges L20 and 2|.

The glass panes lz and rs are separated "at their "edges by a spacingstrip or separator 31; which is preferably of resilient materim such &8rubber. The strip a l (Fig. 1:) is inverted 'T- shaped in cross-sectionproviding a base portion 32 having late-rally extending flanges 33; 81,whicl i' are sated between the outer edges or "the panes 1 2 and I3 andthe webs and I9 or rim members 10 and 11. stem portion as is cositionedbetween the names l2 and :13 and is pro vided with angularly directedrib-llke projections 36 on each face which engages the sum face ofthecpanes. When "the strip isclamped in .position rbetweenfxthe panes.t2 and 13 (:Fig. 3)

the ribs 36 engage the surface of the panes some distance inwardly fromthe edge thereof.

The panes I2 and I3 are separated from the flanges I4 and I5 of the rimmembers I and II by means of glazing strips 31 and 38 as shown in Figs.2 and 3. As illustrated particularly in Fig. 7, glazing strip 31 isgenerally U-shaped in crosssection and is provided with an inner leg 39which is somewhat shorter than the outer leg 40. A recess M is formedbetween the legs 39 and 40 which is adapted to receive the flange I ofthe A lateral groove or, recess 42 rim member I I.

i the rim members.

held in clamping relation with the flanges '20 and is provided in theleg 39 for cooperation with a laterally extending ridge or1ip'43 ontheflange I5 of the rim member II to position the strip 38 ininterlocking relation with the rim member I I. The inner face of the leg39 of the glazing strip 38 is provided with angularly outwardlyprojecting ridges 44, which are adapted to engage the' surface of thepane I3 at a point spaced from the edge of the pane, The ridge members44 are of the samecharacter as the ridge members 35 onthe .spacingstrip3l. When the sash is symmetrical as illustrated in Fig. 1 theglazing strips 31 and 38 may, of course, be identical in construction.

Theribs 36 on separator strip 3I and the ribs 44. on glazing strips 3'!and 38 are initially angularly projecting, as shown in Figs. 6 and 7,and as indicated in dotted lines in Fig. 3. When the structure isassembled as shown in solid lines in Fig. 3, with the glass panes inposition and the frame members I0 and II clamped together by the members22, pressure is applied between the engaging portions of the members andthe ribs 36 and 44 are flattened or distorted, so that the pressure isequalized. The panes I2 and I3 are firmly clamped between the flanges I4and I5 of the rim'members I0 and II by engagement of ridgemembers36 and44 with the surface of the glass and the pressure on the edges of thepanes of glass is applied at points inwardly of such edges throughtheridge members 36 and 44. With this construction they are better able tostand the sudden shocks and stresses which they are frequently subjectedto in use. 7 4 The outer surface 45 of the bight portion of the U-shapedglazing'strip 3'I slopes outwardly and merges with the outer face 46 ofthe leg 40. The'outer face 46 of the leg 40 is provided with angularlyoutwardly projecting ridge members 41.

The-glazing strips 3! and 38 serve the dual purpose of spacing the glasspanes I2 and I3 from the clamping flanges I4 and I5 of the rim membersI0 and I I and also of spacing the entire sash construction between theconventional flashing 48 and 49 (indicated in dotted line in Fig. 3) ontheinside and outside of the vehicle wall in which the sash is mounted,the ridge members 41 engaging the inner surface of the flashing, as

illustrated.

The glazing strips 3'! and 38 cover the flanges I I-and I5 of therim'members ID and II so that there are no exposed metal frame surfaceswhen the sash is installed'in the vehicle wall. The metal frame. membersI0 and II, the flashing 48 and 49 and the glass panes I2 and I3 arecompletely insulated from each other by the separator strip 3| andglazing, strips 31 and 38 to provide an hermetically sealed windowhaving low heat conductivity irrespective of commercial variations inthe thickness of the glass panes I2 and I3. Y

In manufacturing the improved sash two assemblies may firstadvantageously be made-one '2I by the resiliency of the glazing stripsafter assembly of the sash members.

The connecting blocks 22 may be provided with spaced threaded holes 50,which are adapted to receive in threaded engagement a tool or threadedmember by means of which they may be withdrawn from engagement withflanges 20 and 2! when it is desired to disassemble the sash. The sideprojections 24 and 25 of connecting members 22 maybe beveled at 5 I tofacilitate their entry between the rim members It and II. The width ofthe central groove 26 of the connecting members 22 may be varied wherebythe sash may be adjusted to, accommodate panes of glass of materiallydifferent thickness without any alteration in the size or shape of theframe members Ill and II, the spacing member 3| or the glazing strips 31and 38.

The glazing strips'and spacing member for the lass may be made of anyresilient material but they are preferably formed of molded rubber. Therim members I8 and II and the connecting members 22 may be made of anyappropriatelnaterial but are preferably formed of light metal such asextruded aluminum. 7 V

While I have referred to specific materials and details of construction,it will be understood that other materials and details of constructionmay be used within the scope of my invention.
